Resistance on the passenger airbag's second stage firing circuit has climbed past what the restraint controller will accept, and B1B0D is the entry it writes. The system stays disabled until the reading comes back into range.
Squib 2 fires the second stage of the passenger airbag, and its loop has to stay within a defined resistance range for the controller to consider the system ready. B1B0D means the measurement is above that range, so the circuit would fight the firing current at the exact moment it needs to flow freely.
Additional resistance almost always comes from a connection rather than a broken wire, since a break would report as an open instead. Corroded terminals, a spread pin, or a marginal repair splice each add just enough to push the reading over the limit. Vehicles that have had water in the passenger footwell collect these faults years after the leak itself was fixed.
Circuit codes describe a live measurement, so B1B0D reflects what the loop reads today and clears once the connection is restored. Crash data is written permanently at the moment of deployment and stays in module memory through any code clear, which is why it takes a bench reset rather than a wiring repair.
Clearing the module will not reduce resistance in a squib circuit. The controller checks the squib 2 loop on every startup and stores B1B0D again if the reading has not changed. Service the connector or replace the airbag first. Our mail-in reset is aimed at modules carrying crash data or a stored internal hardware fault.
Our lookup shows B1B0D on Dodge, tied to the passenger airbag second stage firing circuit.
Open the yellow connector behind the dash and look at the terminals closely before measuring anything, since visible corrosion often ends the diagnosis right there. Measure resistance across the inflator alone and then through the harness to see which side is adding the resistance. A high reading at the airbag means the assembly needs replacing, and we carry genuine OEM passenger airbags. Related codes: B1B0C, B1B0E, B1B05.
Trace the wiring and connectors first. If the module still holds the fault after the repair, mail it to us and we will clear it.
